sending multiple actions to the same void

i'm using a voice recognizer for some spells in a game and i try to add a new command for every element in the list elements but wen the voice recognizer recognizes a elements name it gives the error :

 KeyNotFoundException: The given key was not present in the dictionary.
 System.Collections.Generic.Dictionary`2[TKey,TValue].get_Item (TKey key) (at <9577ac7a62ef43179789031239ba8798>:0)
 magicspels.recognized (UnityEngine.Windows.Speech.PhraseRecognizedEventArgs speech) (at Assets/scripts/magicspels.cs:107)
 UnityEngine.Windows.Speech.PhraseRecognizer.InvokePhraseRecognizedEvent (System.String text, UnityEngine.Windows.Speech.ConfidenceLevel confidence, UnityEngine.Windows.Speech.SemanticMeaning[] semanticMeanings, System.Int64 phraseStartFileTime, System.Int64 phraseDurationTicks) (at :0)

how can i fix his ? it redirects all the elements to the same void elementscall()
